Description

Subjective information record for linking subjective information about a multimedia content with the content}

The advent of network technologies, such as the Internet and the World-Wide Web (WWW), has led to the availability of large amounts of multimedia content. Multimedia content can be used in digital deliverables, in broadcast data-streams, in personal and expert databases, and the like. The value of this mass of multimedia content depends on the case where it can be found, retrieved, accessed, filtered and managed.

Subjective information on multimedia content is an important factor influencing the selection of content. Subjective information may include ratings or opinions provided by one or more persons for the multimedia content. The selection of multimedia content based on people's opinions, that is, third party reviews, is generally a method associated with social filtering.

Social filtering methods are commonly employed in Internet websites. The users of the website provide details of their preference in a particular domain, for example the purchase of books or music CDs. Users are then recommended to certain products based on these preferences and products purchased by other users with similar preferences.

Media, for example television programs and movies, are often selected using social filtering methods. In selecting television programs, references are often made to program ratings found in TV guides or newspapers.

Movie choices are often made by referring to reviews put by critics whose interests closely match viewers.

Conventional social filtering methods are quite useful for selecting multimedia contents, but they have many limitations. One limitation is that subjective information for multimedia content found in printed materials or in an electronic program guide on the Internet is not directly linked to the content. As a result, user-preferences based on automatic selection or filtering of content are made different. Another limitation is that the author of subjective information is often anonymous. For example, the authors of subjective information found in electronic program guides (EPGs) or local TV guides available from service providers are typically not provided. Thus, the viewer may not be sure that the tastes he or she sees match the tastes of the person (s) who rated these programs. Another limitation includes within the Internet or interactive television applications where there is no mechanism for selecting from multiple reviews of single contents. This is due to the lack of a mechanism to link subjective information directly to content. Therefore, users have no choice in determining what source of subjective information they want to receive to enable their content selection.

The present invention relates to content distribution, and more particularly, to subjective information recording for linking subjective information for multimedia content with content.

The advantages, features, and various additional features of the present invention will appear more fully upon consideration of embodiments that will now be described in detail with reference to the accompanying drawings in which like numbers are used to identify similar elements.

(Summary of invention)

One aspect of the present invention includes a subjective information record for inputting data that enables subjective information about multimedia content to be linked to and represented in well-defined syntax and meanings. The recording includes a field for inputting multimedia contents and data defining a location of the multimedia contents; A field for inputting data identifying an author of subjective information about the multimedia contents; A field for the language of the subjective information; And fields for subjective information about the contents.

Another aspect of the invention includes a method for linking subjective information about multimedia content to content so that the content can be automatically selected or filtered by the user. The method includes providing a subjective information record as described above and linking subjective information generated by the author to content using the subjective information record.

Another aspect of the invention includes an apparatus for searching and filtering multimedia content, the apparatus comprising: a multimedia filter; An electronic program guide for inputting characteristic data describing each multimedia program into the filter; A user profile for inputting user profile and viewing history data into the filter; And a subjective information record for entering data into the filter. This subjective information record enables subjective information about the multimedia contents to be represented in well-defined syntax and meanings and linked to the multimedia contents.

1 is a subjective information record 10 according to an embodiment of the invention. This record enters data pertaining to subjective information about the multimedia contents and thus a plurality for generating a structural representation of the subjective information which is a media review description which can advantageously be used to link the subjective information about the multimedia contents with the contents. Contains the fields of. The fields of the record may include the contents identifier field 20, the subjective information reviewer or evaluation field 30, the subjective information language field 40, and the subjective information field 50.

The content identifier field 20 may comprise two subfields: an identification subfield 22 for identification of subjective information instantiation and a content identification subfield 24 for identification and location of the content. have. The data provided to the content identifier 24 may allow subjective information to be linked directly to the multimedia content, thereby allowing automatic selection / filtering of the content to utilize conventional selection / filtering techniques.

The subjective information reviewer field 30 has three subfields: an organization identification subfield 32 for the name of the reviewing organization, and a description of the contact person for the organization. The contact person subfield 34 for the description and the person (s) subfield 36 for more people rating the description or content of one. The subjective information reviewer field 30 allows a user to determine whether the subjective information of a particular reviewer is used in the user's content selection / filtering process. The reviewer may be an organization such as the Motion Picture Association of America (MPAA) or an individual or a group of individuals such as SISKEL & EBERT. The reviewer field also allows multiple examples of subjective information about a single content by multiple reviewers.

The reviewer field may include additional subfields (not shown) that also identify the reviewer. For example, a subfield may be provided for the location of additional information regarding reviewers. Another subfield may be provided for the type of content that the reviewer (s) is good at ratings and the like.

The subjective information language field 40 is a dictionary identification subfield 44 for three subfields, name of the classification method that lists all languages, and the language used for another subjective information. It may include a language identification subfield 44 for the identifier of and a location identification subfield 46 for the location of the classification method. The subjective information language field 40 provides access to multiple examples of subjective information by the same author in different languages.

The subjective information field 50 comprises four subfields: the dictionary identification subfield 52 for the name of the rating method, and the identification subfield 54 for the identification of the rating that uniquely identifies the rating of the content within the rating method. ), A position identification subfield 56 for the position of the rating method, and a comments subfield 58 for subjective information of the unrestricted free text. The subjective information rating field 50 may be a limited value, such as a predetermined rating method. In this embodiment, the name of the rating method, the unique identifier within the rating method assigned to the content and the location of the rating method are specified in the rating information. For example, the rating may be a numerical rating coined by a review, such as a scale of 1 to 10, where 1 is sleep inducing and 10 is mind blowing. The rating may also be unrestricted free text. In another example, MPAA is the entity used to review and rate content, multimedia content is PG-13 rated, and the MPAA rating method is sufficient on the website www.mpaa.org/rating-scheme. Assume that it is defined (GPG, PG-13, R, etc. and what each of these ratings suggest). It is also assumed that the free text for the content reads as "the graphic effects of this movie are very realistic". The rating for this content looks like this:

Rating;

Dictionary id-MPAA

Rating id-PG-13

Location id-www.mpaa.org/rating-scheme

Comments-The graphic effects of this film are very realistic.

Subjective information subfields refer to it using location information and values in the technique of creating an arbitrary third parity to define their own rating scheme and then rate the content,

The subjective information record of this invention can be used for MPEG 7. MPEG 7 is a multimedia retrieval standard that specifies a standard set of scriptors that can be used to describe various forms of multimedia information. Also described will be a method for associating audiovisual technologies with audiovisual material to be located. Subjective information records of this invention may be organized as MPEG-7 technology schemes and linked to related multimedia content by a mechanism defined by MPEG-7 or any conventional linked mechanism.

The MPEG-7 embodiment of the record of the present invention has also been adapted to the set of metadata techniques defined by TV-Anytime. As shown in Fig. 2, the subjective information record of the present invention is a metadata structure that is recognized and implemented in TV-Anytime for representing and linking subjective information about multimedia content with content for TV-Anytime applications. It may be configured as (60). TV-Anytime is a standard that will set open standards to create audiovisual and other services on consumer platforms with high digital stories.

The ability to represent and link subjective information about multimedia content with content is particularly useful in multimedia content, for example, that searches for and filters systems and devices used in general TV recommenders or personal television (PTV) services, Typically, personal television (TV) recorders equipped with matte storage devices that digitally record multimedia. As shown in FIG. 2, multimedia content that has searched and filtered the exemplary system includes title, channel, and start time. And multimedia according to user file data and user trial history data stored in the user file 80 and data provided by the electronic program guide 90 (EPG) including features describing each multimedia program such as such. General remote for selecting and recording content It includes a media filter software (70). In accordance with the present invention, the user file data may include the user's multimedia review references. The multimedia review references stored in the user's viewing profile 80 and the program data stored in the EPG 90 select the desired multimedia content in relation to the subjective information record 60 for the multimedia content that may accompany the content. May be used by software 70 that has been filtered to record,

In the case of a PTV service provider, subjective information about the multimedia content can be streamed to content in the same way as provided by the record of the present invention or can be used by the PTV service provider using a different transport mechanism. . In the latter case, the PTV service provider may provide an internet website and use an electronic program guide (EPG) as a mechanism for conveying subjective information through the record of the present invention. EPGs with subjective information are periodically downloaded based on the setting of the user's profile, and the television programs to be watched are automatically selected. The user may also decide to select the content manually based on the subjective information displayed for that content, for example as the user browses through the EPG.

As should be clear, subjective information records of the present invention may represent subjective information in a uniform manner, ie with well-defined syntax and semantics, for multimedia content and for the information to be linked directly to the content. In particular, subjective information records provide a means of identifying the producers of subjective information and providing users with the option of using subjective information in a content selection / filtering process based on their preferences.

The record of the present invention also allows multiple legends of subjective information to be linked to a single piece of content, thereby providing the user with a choice of subjective information to select with a content selection / filtering process based on their preferences. For example, reviewers A and B review the movie. Based on previous experience, a user may prefer Reviewer A over Reviewer B for television programs and movie ratings. Thus, the user enters this preference into the user's content selection / filtering profile. According to the above setting of the user's profile, a version of the EPG having a rating of reviewer A is downloaded, and subjective information of reviewer A is used in the user's content selection / filtering process.

Accessibility to multiple legends of subjective information about a single content allows ratings by different reviewers to be combined with other methods to find a single rating. For example, the viewer may want to see only movies that are rated as 80 percent of reviewers.

Another advantage provided by the record of the present invention is that subjective information is made available in multiple languages. This feature extends the range of users who benefit from content retrieval and filtering.

The field of subjective information records of the present invention is not limited to the field described herein.

Although the description of the invention has been described with reference to the above-described embodiments, various modifications and changes can be made without departing from the spirit of the invention. Accordingly, such modifications and variations are to be understood as being within the scope of the appended claims.
